Hello, didn't know where to report this,

Just did a run with the latest mutation patch on the gog / galaxy client,

When I arrived at the assassin, I opened the first door but didn't walk through, used both of my sentries near the entrance of the boss room, to the right of the door ( the ones firing little saws with bleeding effect ) then entered the room, the door animation didn't start, the door didn't close, I think the music changed when getting near the assassin who was static and invulnerable, I opened the door to the exit and couldn't fight the boss at all.

Tried using the turrets outside of the room to trigger the boss but couldn't get it to work.

If anyone wants to try to reproduce the bug / devs want to check this, maybe it's already known, just picked it like 2 hours of playtime.
